 * **Lambert:** Is not affected by roughness.
 * **Lambert Wrap:** Extends Lambert to cover more than 90 degrees when roughness increases. Works great for hair and simulating cheap subsurface scattering. This implementation is energy conserving.
 * **Oren Nayar:** This implementation aims to take microsurfacing into account (via roughness). Works well for clay-like materials and some types of cloth.
-* **Toon:** Provides a hard cut for lighting, with smoothing affected by roughness. It is recommended you disable sky contribution from your environment's ambient light settings to achieve a better effect.
